i Application filed February 3, 1915.` Serial No. 5,885.

Chicago, in the vcounty of Cook and State v of Illinois, have linventeda new and useful Improvement in Railway Crossings, of which thefollowing is a sp'ecication.

My invention relates to an improvementin wheels to 'which thiscast-section of `a railway-crossing is. subjected at the intersection ofthe grooves for the wheel-flanges, tends to fracture it at that point;and when thus fractured the entire section has to be re. placed by a newone.` The impact of the wheels, moreover,l sometimes extends thefracture beyond that point into the body of the casting.`

The object of my invention is to avoid this necessity, by providing thecenter of the sectionvas a removable and replaceable hard-metal insertcontaining the intersecting grooves; and, furthermore, to so supportlv'the (insert thatv the blows of the4 wheels.

against it willnot `be transmitted to 'the remainder of the section,thereby to avoid also ment, and Fig.` 2 is an enlarged section on line2, Fig. 1, but omitting the ties. l .A The crossing-.section `3,provided with the usual wheel-ange grooves, is a castingof manganesesteel. In the center ofthis cast.

ing `is formed an oblong generally rectangu lar hole 4 taperingupwardly. In this hole fits a similarly shaped insert 5, which ispreferably a casting and also oftmanganese steel, containing theintersecting wheelflangev grooves, as shown.l This insert, which fitswedge-like in the hole against displacementv or 'l withdrawaltherefromin the upward direction,v is adapted to be so supported as toprevent the blows of the wheels against it 4from being transmitted tothe -remainderof the section 3, so as to shield the latteragainstrfracture by such transmission. As the preferred means for thussupportin the insert, it is provided with an expand base 6, preferablycast -integr-ally Withfit. The insert seats at the base 6 `on theties 7,whereby .the Vblows referred yto are not only cushioned, therebyreducing this tendency `to fracture the insert atv the intersecting y vgrooves therein, but lalso preventing transf ,i v

mission ofthe impacts to the remainder of the section `3, and therebyremoving all'tendency to fracture of the latter.

Wli'ile I" have` herein, forl the sakefof brevity, shown and ldescribedymyim'provement in its application to a railway-crossing, its advantagesare equallyk great, and the improvement is the same, when applied to ahard-metal railway-frog. I therefore desire to be understood asintending the expression crossing employed in the claims to include afrog as an equivalent structure em-` bodying my invention.

. What I claim as new and desire to secure by Letters Patent is "Y vI 1. A. cast hard-metal crossing-section'provided with an "openingextending through` it at the crossing point, anda hard-metal insertfitting and confined in said opening, said section and insert containinggrooves yfor the anges of wheels traversing the crossing, and saidinsert being supported to take the wheel-blows at the. intersectinggrooves therein and shield the remainder of said section against'transmission thereto of said blows.

2. A cast hard-metal crossing-section yprovided With an openingextending throughit atthe crossing point, and a hard-metal in-` l ,sertfitting andvconined in said openingyand provided `with anexpandedseating base extending underneath vsaid section, said `insertand section containing grooves for the flanges of wheels traversingthecrossing',

3. A cast hard-metal crossing-section provided with` an upwardlytapering opening ,extending through-it at ythe crossing point, `and ahard-metal insert fitting` and confined in said opening vand-providedwith an `expanded seating base extending underneath said section, saidinsert and section containing grooves for the iianges of wheelstraversmg the crossmg.
